We don’t have a disagreement here. Every path leads to 8 limbs, also variations may be different in the beginning.
Also I red Swami Sivananda books and was impressed by his photos.
I find B.K.S. Iyengar way is just right for me. Some people might think it is the way to physical, I guess my way is to find unity through quiet but intense practice. I am thinking to go one day to Pune and study yoga at his center. For now I follow his recommendations on every day regular practice and taking time for key asanas. When I could stand is sirshasana for 15 minutes – I’ll be ready for this journey.
For now I resumed my practice and feel happy that downfall from starting parasite cleanse was short-lived.
